JP128 Posted August 16, 2007 Share Posted August 16, 2007 Ok, if I have a form that submits, how would I see if a word exists? Hmm, I am not sure how to explain this fully.

ToonMariner Posted August 16, 2007 Share Posted August 16, 2007 strstr($_POST['formfield'],$word); or preg_match('/' . $word . '/i',$_POST['formfield']) will find it for you (if you are using get instead of post then use $_GET...)

JP128 Posted August 16, 2007 Author Share Posted August 16, 2007 Yea, but how would I get it to see if it existed on a different page, without going to it?

AndyB Posted August 16, 2007 Share Posted August 16, 2007 Before we all go off at a tangent, why don't you give a better explanation of what it is you really want to do? Some context might help us.

AndyB Posted August 16, 2007 Share Posted August 16, 2007 its hard to explain lol It's even harder to solve!! Do you mean you want to check if a particular word already exists on some named page somewhere on the internet?

JP128 Posted August 16, 2007 Author Share Posted August 16, 2007 ok... lets just say there is a page with the word "true" or the word "false". How would I get that information from that page?

AndyB Posted August 16, 2007 Share Posted August 16, 2007 Here are two hints: #1 - http://ca.php.net/manual/en/function.file-get-contents.php #2 - the more rational a question, the more information you provide, the more likely it is that other people will invest their time in helping. Good luck. Link to comment https://forums.phpfreaks.com/topic/65227-seeing-if-a-word-exists-on-a-form-submit/#findComment-325742 Share on other sites More sharing options...
